Your Bushnell PinPro was designed to provide fast and simple distance measurements to flags and trees in
the golf course. Using Digital Technology the PinPro delivers accurate range performance to +/- one yard
under most circumstances and was designed to work with a specially designed reflective prism placed
on top of the flagstick. The PinPro emits invisible, eye safe, infrared energy pulses. Sophisticated digital
technology instantaneously calculates distances by measuring the time it takes for each pulse to travel
from the rangefinder to the target and back.

The maximum range of the instrument depends on the reflectivity of the target. The maximum distance
for flags with a reflective prism installed is 330 yards/301 meters while for non-reflective objects such
as trees is approximately 450 yards/411 meters. Note: You will get both longer and shorter maximum
distances depending on the reflective properties of the particular target and the environmental conditions
at the time the distance is being measured.
The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the
color, the longer the range. White is highly reflective, for example, and allows longer ranges than the
color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small
target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to
a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted
energy pulses) provides good range while a steep angle on the other hand, provides limited ranging. In
addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit.
The less light (e.g. overcast skies) the farther the unit’s maximum range will be. Very sunny days will
decrease the unit’s maximum range.
